Exynos 5 Octa promises advanced mobile graphics

Samsung Electronics Co. has unveiled the newest addition to its flagship series of ARM-based SoCs. The Exynos 5 Octa is driven by ARM Mali-T628 MP6 cores, which reportedly boosts 3D graphic processing by more than twice the power of the Exynos 5 Dual.

The newest member of the Exynos family is able to perform General-Purpose computing on Graphics Processing Units (GPGPU) accelerating complex and computationally intensive algorithms or operations, traditionally processed by the CPU. This product also supports OpenGL ES 3.0 and Full Profile Open CL 1.1, which enables the horsepower needed in multi-layer rendering of high-end, complex gaming scenarios, post-processing and sharing of photos and video, as well as general high-function multi-tasking operations.

Exynos 5 Octa is powered by four ARM Cortex-A15 processors at 1.8GHz with four additional Cortex-A7 cores at 1.3GHz in a big-little processing implementation. This improves the CPU processing capability by 20 per cent over the predecessor by optimising the power-saving design.

In addition, the multiple image compression IP block inside this SoC successfully lowers the total system power when bringing pictures or multimedia from memory to display panel. This feature results in maximising the usage hours of mobile devices with a high-resolution display such as WQXGA (2500x1600), in particular when browsing the web or doing multimedia application requiring the frequent screen refresh.

This new Samsung processor also features a memory bandwidth of 14.9 gigabytes per second paired with a dual-channel LPDDR3 at 933MHz, enabling an industry-leading fast data processing and support for full HD Wi-Fi display. It also incorporates a variety of full HD 60 frames per second video hardware codec engines for 1080p video recording and playback.

The latest Exynos 5 Octa line is currently sampling to customers and is scheduled for mass-production in August.
